Abstract (en)

[origin: US4476804A] A process and apparatus for coating particles, particularly particles of medicinal drugs. The apparatus has a rotating drum provided with a perforated cylindrical center section. Particles to be coated are introduced into the interior of the drum and form a layer in a lower quadrant of the cylindrical section during rotation of the drum. A spraying device is located in the interior of the drum for coating the particles with an appropriate mixture or solution. A device is positioned adjacent the portion of the drum containing the particles for introducing gas through the perforations into the layer of particles so as to dry the particles. A device also is provided for removing gas from the drum through the perforations. The device for introducing gas can be separated from the device for removing gas by a central partition, with both devices being carried by a common support. Also, it is possible to introduce gas into a portion of the interior of the drum that is spaced from the layer of particles.
